I'm not an electronics or mechanical design degree student.
I'm not a welder, machinist, rocket scientist or nobel prize winner.
I don't hold any patents, nor have I ever considered applying for one.
I'll probably never fly a space shuttle, eat an ostrich burger or launch a nuclear missile at a small unsuspecting country. I couldn't tell you how to build an H-bridge electronic circuit or how to determine the meta-key-balance-resistance of your thermonuclear thingamajoggle. I'm just a guy with some tools, who likes to take things apart to see how they work and can barely put them back together.
